right and I was looking at the 2 gal ebb and flow 6 site add on kits for the $500 system are only $70 shipped.. Which is a little over $10 per site but each site has 2 buckets and all plumbing already done.. and they fit together and look nice.. The 3.5 gal buckets are $5 each (i would need two) and then another $2 each for the fittings and tubing..

would 2 gal of hygroten each be enough to grow 6 footers?
